摘要： The invention pertains to a subfloor for use in egg laying cages wherein the subfloor prevents caged fowl from catching their spurs in the conventional floor grate. The subfloor is formed of longitudinal and transverse members spaced apart a distance equal to the spacing of the corresponding elements of the cage floor. However, the subfloor is so located upon the cage floor that the resultant floor openings are only one quarter the area of the previous floor openings providing superior support for the bird's feet and preventing spurs from being caught in the cage floor. As the subfloor is loosely supported upon the cage floor, relative movement therebetween produces a self-cleaning action.
